Twenty eight (28) M224, 6CMM Mortars have been released to the field as of 12 Mar 82. These weapons were fired at Ft. Steward, CA and Ft. Imwis, WA. , A total of 18,000 rounds have been fired in these weapms, of which 6,000 were M720 6CMM Cartridges (new KE Round) . To date, there have been a total of four ' Range Indicator Asse. blies (RIA) failures of which two should be considered chargeable and two should be considered non-chargeable as reliability failures . Se chargeable RIA failures include s (1) which failed during firing in Minnesota in December 1981, and (1) which failed during a jump in February 1982. De nz-chargeable f ailures include s (1) which was accidentally stepped-on while re- moved from the handle in Jul 81, and (1) which broke when a weapon was accidentally drcpped from a height of approximately (5) feet in Sept 81. These weapons were utilized by the U.S. Army Ranger Battalions. b. During reb 92 this cercand initiated a modified acceptance test *.o 100% proof test the M224 Mortars in lieu of the nomal 204, which contain four tritium sources of .8 curies each in the Range Indicator Assembly (RIA) . c. This proof testing involved firing mortar rounds at charges higher than is used in normal service, with the innseidate objective of accepting 698 mortars for delivery to the Marine Corps. d. Ut111:sticri of this overtest procedure will screen marginal RIA's, resulting in a very minimal number which could eventually break during nonnal field use. - .' - . . SUM 40a .

The license includes a reqJirement for 100 percent test firing of M224 Lightweight Company Mortar (LWCM) in lieu of the usual 20 percent testing, (reference Ic). This amendment request is asking for relief from this requirement. 3. The 100 percent test firing requirement was added to the license since breakages of tritium lamps occurred in the range indicator assently (RIA) of the LWCM during preliminary testing. At that time, it was anticipated that the test firing would screen out marginal RIAs and preclude a high breakage rate in the field. 4. Since the initiation of the 100 percent test firing, data has been compiled (attached as encl 3) which shows that virtually all the breakages occur when the LWCM is fired at charge 5 and hipier. Users in the field do not use a charge higher than charge 4 Each LWCM shell is provided with only four propellant increments that are located between the body and fin of the mortar. Unless additions 1 charge increments are manually added to the mortar shell, personnel in the field cannot fire at a charge 5 or hi@er setting. | 6 17540 Y - - ._ _ _ - - - - . -_--- - _ _ . _ - - - _ @ (- ,. DRS>C-SF (R) SWICT: Request for Amendment to Nuclear Regulatory Commission (EC) License B4.12-00722-06 Additionally, range data in the firing table of the operator manuals for the LWCM include information for charges 0-4 only. The charges 5 and higher used during testirg sinulated " worst case" conditions. Therefore, this comand feels the breakage rate in the field will be lower than that experienced during testing. 5. h.e original premise that the 100 percent test firing would ccreen out : marginal RIAs is no longer valid, since the problem is in the design of the ] item and is not the quality of manufacture. A Product Improvement Program (PIP) to cormct the desicp deficiercy has been proposed and is scheduled for ; funding in the FY 85 budget. Therefore, to continue the 100 percent test : firing serves no useful purpose whatsoever. The bmakage rate in the field is expected to be far lower than what is experien:ed during testing due to the higher ctiarges used in the testing. 6. Additionally, the cost to 100 percent test fire LWCMs for the thrine buy . exceeded $900 per weapon. Breakdown of the costs from TECOM is attached as encl 4. thless the 100 percent requirement is deleted from the EC license, l this command would have to spend over $900 per weapon to test an item when y ] the failure rate and cause of failure are already known, i ; j 7. A previous submission of this amendment request was rejected by HQ, [ ;. DARCOM (refererce Ib). Additional requirements were imposed, many of which this command feels are not applicable to this amendment request. These are j addressed in ercl 5. i ' ! ! 8. This amendment is simply askirg for relief from the: 100 percent test ! firing requirement. Request that serious consideration be given to allow the ! WC to review this amendment request. Testing at the 100 percent level is no longer justified, is not cost effective, and provides no additional safety i for the user. | FOR TFE COMmtOER: . M 5 Enc 1 N as olondl,t Chief of gf [ ! i i ! !

Twenty eight (28) M224, 6CMM Mortars have been released to the field as of 12 Mar 82. These weapons were fired at rt. Steward, CA and rt. IAvis, WA. A total of 18,000 rounds have been fired in these weaper.s, of which 6,000 were M720 6CMM Cartridges (new RI pound) . To date, there have been a total of. four j Range Indicator Assemblies (RIA) failures of which two should be considered chargeable and two should be considered nm-chargeable as reliability failures . The chargeable RIA failures include s (1) which failed during firing in Minnesota in December 1981, and (1) which failed during a jump in February 1982. The ncn-chargeable fa11u2Ss include s (1) which was accidentally stapped-on while re- moved free the handle in Jul 81, and (1) which broke when a weapen was accidentally dropped frein a height of approximately (5) feet in Sept 81. These weapons were . utilized by the U.S. Ar ny Panger Battalions. b. During Feb 62 this comand initiated a modified acceptance test to 100% proof test the M224 Mortars in lieu cf the normal 204, which contain four tritium sources of .8 curies each in the Pange Indicator Assembly (RIA) . c ' Ns proof testing involved firing mortar rounds at charges higher than is used in normal service, with the iseneidate objective of accepting 698 mortars . for delivezy to the Marine Corps.

Per request, subject QOR has been reviewed and the following comments are provided: a. AARADCCN technical representatives visited the USMC unit at Camp LeJeune la January 1983 and examined the daar. zed material. Meetings were also held with * representatives of the USMC Logistics Base. The breakages are considered to be known reliability failures and not a safety issue. . ' b. A New Start, FY85 Product laprovement Program (PIP) has been syy~ 4 . in which the Range Indicator Assembly (RIA) will be redesigned to significantly improve its strength characteristics and thus increase field reliability. Perocasted availability of modified RIA's is in the 1987-1988 timeframe. c. lintil such time sa the modified RIA's are available, it will be necessary to obtain spares via the normal supply systes. An adequate quantity of spare RIA's has been procured in anticipation of the previously indicated marginal reliability condition. 3. For additional information, contact Harvey I.

The test firing was perfoited at Aberdeen Proving Ground from February 1982 to May 1983. There were two types of test firing, proof and screen. - Proof testing cmsisted of five romds, romd one at charge two; round two at charge four; romd three md four at charge five; and romd five at higher than charge five. There were three romds fired in the screen test. Romd one was at charge four; round two at charge five; and romd three at higher than charge five. Eighty percent of the cortars were screen tested and 20 percent were prcof tested. . Although the field dces not use a charge higher than four, the mortars were fired at charge fise and higher as a safety test to the mortar barrel to simulate "wcrst case" situatims. Of the 750 weapons tested, there were 84 failures, or 11 percent failures. There were 82 failures at charge 5 and higher and cnly two failures at maximum field charge, charge four. The data lists the failures that occurred during the test firing. Colum one is the date of the test firing. Cclum two indicates the nurter of mortars firec. The "P" is the number proof tested and "S" is the nmcer screen tested. Coluen three is the serial numbers of the mortars that experierced breakages of the RIA lamps. Colum four is the number of broken lam;;s per assemoly. There are four tritium lags per RIA, each lam centaining 0.8 curies maximum for a total of 3.2 curies tritium per RIA. Colen five is the remd necer when the breakage occurred. Colmn six is the charge when the breakage occurred. The "NA" indicates the pressure reading was not availadle. Colum seven is the location of the broken lamps, T= Top, B= Bottom, L Left and R=Alght. Colen eight indicates the weapon pressure in pomds per scuare inch. Page three of this data indicates the expected pressures for the M720 and M49A4 ammitim. The M720 ammmiticn was used for the testing and it is the amunition the Army proposes to use when the mit is fielded. Colum nine is the results of wipe tests of the RIA after a breakage occurred in comts per minute. This indicates the amomt of removable ccntamination. The contaminatim has been limited to the handle of the RIA. The rest of the mortar has not been affected. When a failure cccurs, the handle is simply rencved, placed in a plastic bag, and sent to a licensed depot for repair. Contaminated items are not fielded. . .

Additional Information Requested by HQ, DARCOM 1. A previous submission of this amendment request was rejected by HQ, DARCOM,1st Ind, 28 Oct 83, to ltr, DRSMC-SF (R), HQ, AMCD)M,12 Aug 83, SAB. DARCCM's additional requirements are addressed below. 2. In paragraph 1, the statement "Unfortmately, the range indicators w::re procured without having gone through the testing normally performed on other radioactive conmodities (M700-64)." is not true. The lanps on the range indicat ar assenbly were tested to meet the drawing specifications as required in the current MIC license EH.12-00722-06. The specification tests include a shod < test where the lamps are exposed to an immediate -800F and after returnirg to ancient, an immediate +1600F for a period of 8 hours at each temperature. Quality control sampling procedures, performed IAW title 10, part 32.110, resulted in zero failures. This further illustrates that the breakage problem is a result of desigi and not manufacturer's poor quality in production sirce the lanps meet drawing specifications. 3. In paragraph 1, the statement "the RIA tritium lamps can fail on even the first use" is not substantiated. The data used to smport the amendment request shows that the RIA lamps are unlikely to break at field charges. ' 4. In paragraph 2, the statement " field use of zone 3 with the new rounds ' could exceed the impact of zone 5 during testing" is conjecture and , unsubstantiated. First, the "new" round and test round are one and the same ; - the M720 round. Secondly, the data used to s m port the amendment request , showed only 2 failures at charge 4 out of 750 weapons. Therefore, it is logical to assume that breakage at charge 3, at which test firing was not performed, is even more unlikely. t 5. In paragrmh 3a, HQ, DMCOM requests that the amendment proposal be , sigled by a menber of the AMCCOM Connand Grom. This amendment proposal is , sig1ed by the Chief of Staff. j 6. In paragraph 3(b), HQ, DARCOM requests that the smporting data be made more understandable. A cover sheet has been added to the attached data. t 7. Paragrmh 3(c), requests that if any testing will be conducted, the test procedures be stated along with what constitutes failure and actions to De : taken in the event of failure. This amendment request is sinply asking for ! relief from the 100-percent test firing requirement. This heac4uarters does I not propose to eliminate all testing, nor to propose additional testing. The testing required to' meet drawing specifications, which includes shock tests and leak tests, will continue. 8. In paragraph 3(d), HQ, DMCOM requests a mathematical study to predict the maximum breakage in the field and the predicted exposures. It is . anticipated that until the modified RIAs are available, the field may , | experience occasional breakage of the tritium lamps due to firing. ' t Calculations are attadied (encl 1) whidi indicate that any tritium lamp l breakage of the RIA due to firing will present no health risk to the user or to the environment. The field breakage rate is expected to be low and is l 4 % 40 , i . ,.. considered to be a known logistics and reliability problem and not a safety issue. To ease the logistics problem, 300 spare RIAs are available for use, until the redes'icped RIA is available to the field. 9. In paragraph 3(e), HQ, DARCOM requests the action to change the desicy of the RIA. The start of the PIP is scheduled for Dec 84, with fielding by attrition scheduled for Dec 86. 10. In paragraph 3(f), HQ, DARCOM requests the instructions to be given to users if it is planned to limit the fielding of the LWCM to a smaller charge than zone 4 Again, this amendment request is only for relief from the 100- percent test firing requirement. Limiting the field charges is not only unnecessary but such action may impede the readiness capability of the LWCM and is not relevant to this amendment request. 11. In paragraph 3(g), HQ, DARCOM requires the amendment request be staffed through the chairman of the Tritium Committee, TECOM, TRADOC, FORSCOM, and other MC3Ms. The corcurrerres of the commands are attached (ercl 2). 2 Encl as _ k % | 2 , 395A0 t . . .. <- . . . _ _ , _ - .. - . ..- . - . . -- _ , i.* ..

Reference la forwarded subject request for amendment signed by HQ, AMCCOM Chief of Staff. Enclosed to reference la was various back-up data and responses to an earlier inquiry.from your office. I 3. References 1b and Ic established the basis of concern that a response offered ! in enclosure 5 (paragraph 2) of reference la could be judged incomplete by the | NRC. The response in question indicated that the system range indicator contain- ' ing tritium lamps was subjected to shake, rattle, and roll testing under extreme temperatures. The potential issue with this response is that there is an absence of any reference to specific test data sources. 3 4. To avoid any restaffing action, this office offers the following information | ; to supplement that already provided in reference la: i a. Extrece temperature shock testing of the range indicator assembly wac successfully accomplished in TECOM design testing leading to type classification. This test data can be found in TECOM Test Report No. 8WE-500-LCM-004, titled Vol II DT II LWCMS, Aug 76, for RDTE Project No. 1T564602 D029. __ | % - - . - . . l l . .

As part of First Article Initial Production Testing (FAIPT) philosophy, end items are subjected to test sequences performed in DT. The FAIPT conducted for the LWCMS including the range indicator assembly configuration incorporated extreme temperature shake, rattle, and roll testing. Reference ld is enclosed and exhibits the types of testing performed while finding that the LWCMS exhib- ited no deficiencies. The actual test report has not been published at this time, and the test plan, referenced in reference Id, is available at HQ, TECOM. 5. It is hoped that the above information is satisfactory.
